S-92012A589 10-24 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional Strength and Durability: Made from high-grade alloy steel with a tensile strength of 140,000 psi and Rockwell C32 hardness, ensuring reliable performance under heavy loads and reducing the risk of fastener failure.
• Superior Corrosion Resistance: The black oxide finish provides a protective layer, enhancing longevity in harsh industrial environments and minimizing maintenance needs.
• Precise Shoulder Fit for Stability: Features a 1/4" shoulder diameter with a tight tolerance (-0.001" to 0") and precise fit, enabling accurate alignment and reducing wear in rotating assemblies.
• Easy Installation and Removal: Hex socket drive (1/8" size) allows for secure tool engagement, speeding up assembly and disassembly while preventing stripping.
• Wide Compatibility and Standard Compliance: UNC coarse threads with Class 2A fit ensure easy integration with standard components, while RoHS 3 and REACH compliance meets global environmental regulations.
• Optimized for High-Stress Applications: The 3/4" shoulder length with minimal tolerance (0" to 0.002") provides consistent spacing and support, ideal for machinery requiring precise axial positioning.
• Cost-Effective Maintenance: Durable materials and finishes reduce replacement frequency, lowering long-term operational costs in demanding settings.

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address common industrial challenges, such as misalignment and component wear in rotating machinery.
